16 Claims.

The invention relates to meat slicing machines and particularly to slicing machines of the continuous type employed for the cutting of slabs of bacon into strips. Heretofore there has been employed a slicing machine having a knife or cutter movable in a vertically and transversely extending cutting plane for severing the several slices I of bacon one after the other from a slab of bacon fed longitudinally thereto and while the slabs of bacon are supported on a horizontally, transversely and longitudinally extending supporting table with which the cutter is functionally associated.

It has also been old in machines of this type to have a supporting table constructed so that it is provided by or with .a suitable moving conveying element or other suitable means for effecting longitudinal forward movement of the slabs of bacon to the knife or cutter. It has also been old to have associated with such supporting table a spring pressed holding down means for maintaining the slabs of bacon in contact with the supporting table while the slabs are being conveyed along the same in a longitudinal forward direction.

Frequently in the holding down mechanism as heretofore employed there has been used a series of longitudinally spaced, transversely extending rollers located above the supporting table and mounted so that they are normally pressed towards the table but so that they can individually yield in a direction away from the table. In such constructions there has been left a considerable gap between the foremost of these pressing down rollers and the rear face of the knife or cutter of the machine.

In an earlier filed application, to-wit, application Serial Number 635,333 filed September 29, 1932, there is shown a spring pressed holding down finger construction which is incorporated in the space between the forward transversely extending pressing down roller on the one hand and the rear face of the knife or cutter on the other. But in said application these fingers, the spring pressing means therefor, and the other movable parts associated therewith are all mounted upon transversely extending shafts or bars which are mounted in vertical upstanding side portions of the main frame but in such a manner that said transversely extending shafts or bars do not have any vertical movement in respect to the table. According to the construction of said application however should one desire to effect an adjustment of the pressing effect of these fingers the same is accomplished by successively adjusting a spring mechanism associated with each finger.

In said application the knife or cutter thereof effects the successive severing of the slices from the bacon slabs by a cutting operation which comprehends a shearing action and also a transverse or lateral drawing action with the result that the cutter to a certain extent tends to distort in a lateral or transverse direction the bacon being sliced and these fingers just referred to serve to guide the slabs of bacon as they move under and in engagement with the fingers in a forward longitudinal direction and to hold the slabs of bacon against lateral distortion during the cutting operation.

These fingers are mounted so that they can yield in a vertical direction according to the uneven service condition or varying thickness of the slabs as they are moved towards the cutter but they are mounted so that they do not yield laterally.

The present invention contemplates the employment of transversely spaced guiding fingers or members that are arranged in the immediate vicinity behind the cutting knife and the mounting of said fingers or guides upon a transversely extending supporting bar or frame that is vertically movable and positionable as a unit towards and from the supporting table. The fingers or guiding members of such new construction may be of the type shown in said pending application or may be of other types. In the broadest aspects of the invention applicant contemplates employing in connection with a bacon or other meat slicing machine, and more par- .35 ticularly in connection with the longitudinally extending supporting table and transversely moving cutting knife thereof, a series of transversely spaced guiding fingers or members having meat engaging portions thereof that extend in a general longitudinal direction and which guiding fingers or members are as a whole mounted upon a common frame or supporting bar which is positionable as a unit towards and from the supporting table, whereby a ready adjustment of the fingers or guide members can be readily accomplished according to the general thickness of the bacon slabs or other meat material to be sliced in and by the machine.

According to one embodiment of the invention these fingers or guide members are preferably spring pressed in a forward downward direction so that they can yield in an upward direction according to the inequalities of the bacon slabs or other meat material passing through the machine.

A further object of the invention is to provide a construction in which a series of transversely spaced guiding members are carried by but yieldably associated with a vertically positionable frame or supporting member so that by a single vertical adjustment of the supporting bar or frame a desired positioning of the spring pressed fingers as a set can be readily accomplished.

In the embodiment of the invention illustrated in the drawings these spring pressed fingers thus carried by and from the vertically positionable supporting bar or frame are preferably individually mounted and controlled by individual springs so that any one finger or guide member can be individually adjusted as to its pressing effect.

With these and other objects in View, the invention consists in the construction and novel combination and arrangement of parts hereinafter fully described, illustrated in the accompanying drawings and pointed out in the claims hereto appended, it being understood that various changes in the form, proportion and minor details of construction, within the scope of the claims, may be resorted to without departing from the spirit or sacrificing any of the advantages of the invention.

As illustrating one manner in which the invention may be realized reference is made to the accompanying drawings forming a part of this specification.

Figure l is a vertical longitudinal sectional view of the forward end of a slicing machine having a longitudinally extending supporting table along which bacon slabs are fed in a forward longitudinal direction to a cutter that revolves about a longitudinally extending shaft, and which cut ter or knife has the cutting edge thereof arranged so that it operates in a transversely extending cutting plane and effects the cutting operation by the combined effect of shearing and drawing cutting actions. In said figure there is shown a series of longitudinally spaced, transversely extending spring pressed holding down rollers and also a finger and guide construction which is located between the spring pressed holding down rollers on the one hand and the cutter on the other, and which spring pressed fingers or guides are carried upon and by a vertically positionable, transversely extending supporting bar or frame.

In said figure there is also indicated means operatively associated with the vertically positionable supporting bar or frame on the one hand and the main frame of the machine on the other, whereby the supporting bar or frame is readily moved to any desired vertical position for adjustment and whereby it is held in said adjusted position.

Figure 2 is a vertical front view of the machine shown in Figure 1, a part of which is broken away, the knife being omitted to permit a clear showing of details.

Figure 3 is a vertical transverse view partially in section, showing the construction of the mechanism that includes the spring pressed fingers, the transversely extending supporting bar or frame by and from which the fingers are carried, the mode of mounting the supporting bar or frame in respect to upright portions of the main frame of the machine and operating mechanism comprising gears and screws, whereby the supporting bar or frame can be vertically adjusted and held in adjusted position in respect to the main frame.

Figure 4 is a vertical longitudinal sectional view taken as on the plane indicated by the line 4-4 of Figure 3. The parts shown in Figures 3 and 4 are on a larger scale than they are in the other views.

Figure 5 is a general side elevation at a much smaller scale than that of Figures 1 and 2 and in Figure 5 there is shown practically the entire cutting machine construction and in respect thereto a portion of an endless delivering conveyor usually employed in connection with the machine.

Reference will now be made to the drawings in detail. In Figure 5 the slicing machine as a whole is designated by I. It comprises any suitable framework or main frame as 2 that supports at the rear or feeding in end thereof a portion 3 of a receiving and supporting table 4 which also comprehends an endless table member 5 which may be considered, as part of the feeding mechanism whereby slabs of bacon or other meat products are fed in a longitudinal forward direction to the cutter or knife 6 of the machine. This endless table member 5 may be considered as part of an endless conveyor that is relied upon for feeding the material or meat products to be sliced, such as slabs of bacon, forwardly to the cutter or knife 6. At the front end of the machine there is provided an anvil as 'i constituting the forward end of the table structure and which serves to support the forward end of the slab of bacon while being cut.

The cutter or knife 6 of the machine is secured to and carried at the forward end of the cutter carrying shaft 3. The frame of the machine supports any suitable type of motor 9 which operates the shaft 8 through any suitable gearing as H] and I l.

The endless conveying mechanism 5 is operated from the cutter carrying shaft through the medium of chain and gear mechanismin effect through gear mechanism comprehending such parts as l2, l3, l4, l5, l6 and I? all of which parts are suitably supported but as to which detailed description thereof is not considered necessary, and which function to drive through the medium of the cutter carrying shaft 8 the endless feed conveyor 5.

The fixed rear portion 3, the endless conveying member 5, and the anvil 1 and the parts associated therewith collectively constitute a longitudinally, horizontally and transversely extending supporting table upon, along and by which slabs of bacon to be sliced are fed in a general forward longitudinal direction to the cutter. The machine is provided with any suitable means as the longitudinally spaced, transversely extending rollers I8 which are spring pressed as by springs l9 so as to normally force the slabs of bacon towards the table during the period they are being conveyed forwardly towards the cutter. These rollers are sometimes referred to as yielding or spring pressed holding down members b cause they function to press the slabs of bacon downwardly towards the supporting table and hold them against the same.

The machine is also preferably provided with any suitable endless discharge mechanism as 2!] which is relied upon to convey the sliced material from the machine as and when produced. This endless conveying mechanism 20 is generally of the continuously moving type. An inspection of Figures 1, 2, 4 and 5 will make it clear that a relatively long space exists between the foremost spring pressed roller l8 and the rear face 2| of the cutter or knife 6. The knife is constructed so that it functions not merely by a downward shearing action but by the combined downward shearing and lateral drawing actions. The drawing effect is produced because the knife has a cutting component in a transverse or lateral direction. The cutting effect by the knife tends to cause certain distortion of the material being cut or sliced unless that material is supported against the forces tending to distort it and particularly against the forces tending to distort it in a lateral transverse direction.

In order to insure that the bacon slabs or whatever meat is being cut shall be properly guided and held in place the finger construction generally designated as FC has been incorporated in the machine between the pressing rollers 48 and the rear face 2| of the cutter or knife 3.

This finger construction generally designated by FC comprises a vertically adjustable and positionable transversely extending supporting bar 22 constituting a vertically adjustable and positionable supporting frame member upon and by means of which there is carried a series of elements as 22 22*, 22, etc. and these elements comprise a series of fingers or guide members 23.

An inspection of Figure 2 discloses that ten of such fingers are illustrated. These fingers are mounted so that the lower or forward ends thereof can yield in a vertical direction relative to the supporting bar or frame by which it is carried and it will be observed that each finger has a meat engaging portion 23 at the lower forward end thereof which extends in a general longitudinal direction and each finger is mounted so that it can move in a vertical longitudinally extending plane, and each is also so mounted that it does not have any substantial movement or play in a lateral transverse direction. Because of this mounting they are free to adjust themselves according to the varying thicknesses of the slab of bacon engaged thereby but so that they oppose any movement in a lateral transverse direction.

In the construction shown the transverse supporting vertically adjustable supporting frame includes the bar 22 and the depending side portions 22 in which there is mounted a transversely extending main shaft 24 of the finger construction and a transversely extending auxiliary shaft 25. The main shaft has mounted thereupon a series of transversely disposed long arms 26 each of which is mounted on the shaft so that it can have a limited angular movement in respect to the shaft. The extent of this angular movement being limited by a stop pin 21 carried by the shaft 24 and which extends into a slotted portion 28 of the hub that is on and constitutes a part of the long arm 26.

The outer end of this arm 26 is pivotally connected by a pin 29 to the middle portion of the finger 23 corresponding thereto. There is also mounted upon the auxiliary shaft 25 a series of short arms 30, each of which is free to have angular movement in respect to the shaft upon which it is mounted and the free end of this arm 30 is pivotally connected by a pin St to the rear or upper end of the finger corresponding thereto. Each pin 3| has a roller 32 which is continuously spring pressed in a downward direction by a plunger 33 which is normally urged in a downward direction by a spring 34 corresponding to the plunger.

The supporting bar or frame 22 previously referred .to carries the hollow bolt or bushing 35 which is locked in place by the collar or look nut 3B, which bushing 35 can be adjusted to regulate the pressing effect of the spring 34 and thereby the pressing effect of the finger controlled thereby. Each finger, corresponding arms, plunger, spring, bushing, etc. constitutes the series of elements 22 22 22, etc., previously referred to, and it will be manifest that the pressing effect of each finger or guide member can be regulated at will independently of the other fingers.

The main shaft 24 is normally held against rotation in one direction by a pin 3'! therein near one end thereof which normally engages a pin 38 which is carried in and by a side member 22 of the supporting bar near the lower end of the latter as is clearly apparent from the lower left hand portion of Figure 2.

The result of this construction is that the stops 2'! on the shaft 24 can serve to determine the lowest position of the free ends of the long arms 26 and thereby the lowest position of the ends of the fingers 23 in reference to the supporting bar or frame 22. A handle construction 39 is provided for effecting at will a turning movement of the main shaft 24 for the purpose of causing an elevating of the fingers 23 in reference to the supporting bar or member 22. It will be manifest from an inspection of the figures of the drawings and particularly Figures 3 and 4 hereof that the fingers 23 are all supported on and carried by the frame comprising the transversely extending sup porting bar 22 and the side members or brackets 22 Therefore when this frame 22-22 is raised orlowered the fingers 23 as a set are correspondingly positioned.

This transversely extending slidable supporting frame 22-- 22 more particularly the side members thereof 22 are slidably mounted in vertically extending upright bracket members or upright frame portions 40. The side portions 22 of the supporting frame 2222 are maintained in sliding position with respect to the upright brackets or frame portions 40 by means of gibs 4| which are secured in place as by means of the screw bolts 42.

This finger construction as a whole is vertically adjustable and positionable by means of a mechanism collectively designated as 43 and which has parts operatively associated with the uprights 49 of the main frame on the one hand and the vertically positionable supporting bar or frame member 22 on the other hand. This operating mechanism 43, just referred to, comprehends a shaft 44 which can be turned by hand by means of a hand wheel 45. This shaft 44 is rotatably mounted in and movable with the supporting bar 22 and it carries thereupon at or near each end thereof a gear or worm 46 which is secured thereto as by means of the pin 41. Each of these gears or Worms 46 meshes with a corresponding worm wheel 48 that provides a nut which turns upon a corresponding fixed vertically extending screw 49.

Each worm wheel 48 is maintained in place with respect to the supporting bar or frame 22 because of a pocketed portion 53 provided at or near each end of the supporting bar and within which the worm wheel 48 corresponding thereto is located and it will be noted that each vertical screw 49 is fixedly secured at 51 to a member or portion which is a part of the gib construction that is fixedly secured to the uprights 40 of the main frame. Each vertically extending screw 49 is maintained in place and against rotation by means of a pin 52.

From an inspection of Figures 3 and 4 it will be manifest that a turning of the handle readily effects a desired vertical adjustment of the finger construction as a whole. It will also be observed that the construction is such that upon release of the handle the worm and screw construction described automatically efiects a locking and secure holding of the supporting bar 22 and fingers carried thereby in adjusted position in respect to the supporting table upon and along which the bacon slabs are fed to the cutter. By this arrangement one is enabled to set the fingers as a whole so that they have the desired guiding and pressing effect in respect to the slab of bacon or other piece of material engaged thereby.

It will also be observed that the pressing effect of any one finger can be regulated or determined by the individual adjustment therefor without altering the pressing effect of any other finger. Applicant has shown in association with the supporting bar a particular guiding and holding finger construction.

Within the broader aspects of the invention there is contemplated the employment of other forms of guiding and holding fingers from those shown and which guiding fingers may or may not be spring pressed dependent upon the particular feature in this regard that may be desired. However in the more specific aspect of the invention there is contemplated the employment with the adjustable positioning and supporting bar of guiding fingers which can be relied upon to assist in the guiding of the bacon slabs as they pass in a longitudinal path to the cutter and to the employment of such fingers to oppose any transverse or lateral distortion during a cutting operation.
